These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ho Yay: Yes, but really only by today's standards; the notion that "close friends of the same sex = homosexual tension" is a modern idea that would have never occurred to Stan and Babe.
However, the silent short Liberty involves them breaking out of prison, changing out of their uniforms and into civilian clothes, getting each other's pants by mistake, and then repeatedly being caught in public dropping their pants while trying to swap them, leading to hilarious amounts of Not What It Looks Like.
Seinfeld Is Unfunny: Subverted-despite the films being made in the 20s and 30s, chances are that if you show one of their best works to groups of teenagers, adults or children who have never seen them before, they'll all be laughing within a few minutes.
Values Dissonance: Bonnie Scotland has not aged well at all-it was set during a time when the British Empire still ruled, and it shows the mutinying Indians as evil villains, when they were in fact fighting against British racism themselves. Similarly, Pardon Us has the boys donning blackface makeup to hide on a (rather happy) cotton plantation, of all things.
